Análise da influência do processo de pintura na dureza e resistência mecânica da liga de alumínio A356

Abstract

The unique characteristics that aluminum, the most abundant metal in the world, presents, is a great attractive, especially for the automotive industry, because it presents good resistance to corrosion, great thermal conductivity, low density and high capacity of energy absorption. Thus, the main issue of this work is to show the influence that the painting process can have in the thermal tractable alloys, through the collection of a A356-T6 alloy sample, where experiments were carried out in order to show possible changes in its properties after the painting process, evidencing the influence on its mechanical characteristics. After this process, it was concluded that the process causes changes in its mechanical properties, with 30% of its tensile strength increased and 27% of its elongation decreased.
